There are websites that will sell you data about the car history and who it's registered to. They buy the data from the DVLA. It's how parking companies find out where you live when they want to send you a penalty notice.
However, I think we're derailing the OPs thread.
You have to be approved by the Home Office before your company has access to apply for DVLA records, and it costs money.
A villain might conceivably clone his plate if they see him driving about, but they wont faff about with the address. Theyll use it to commit crime or avoid parking tickets for a couple of days, and on to the next plate.
However, it's a dodgy game. ANPR isn't daft and notices straight away if a car is in Aberdeen at 11:03hrs and then in Knightsbrodge at 11:05hrs - ANPR is now so widespread and flags cloned plates so readily that it is not as popular as it once was.
Dealers cover plates for different reasons. Sometimes so cars being transported dont ping ANPR or toll cameras. On the forecourt they do it to hide the cars age, forcing you go and enquire with the nice salesman, who then reels you in...
Unless it's a very unusual car, a villain will just walk up the road and note registrations, or stand on a bridge over a busy road and let the plates come to him.
Anyway, enjoy the free bump!
